For this test I spent some time (And platinum) Making the best possible set of gear I could find for pure -saves. This included replacing all gear that had saves V Breath, Rods, and petrification with Pure saves or at least saves V spell.

I was able with casting bless on all gear and bless on myself to get my saves to -232, which is not the absolute lowest it can get, but its pretty damn close. With these saves I went about attempting to enchant a stack of beginner lances from Shadowdale. I started with a pile of 20 lances. After these I Also attempted the same with a pile of Hero lances to rule out any affect item level may have on the enchanting process.

Durring the testing I was unable to get a single lance beyond 9/9 rolls with either beginner or hero lances. A few weeks previous with normal gear and saves at around -100, I was able to enchant 3 beginner lances to 11/11. This itself proves that saves have no affect on Enchanting.

With this character setup My ending HP base was Approximately 6400 HP. As this is quite high for a starting base HP, I believet hat this proves that hunger has zero effect on Base HP, but also raises a new question yet to be truly tested. Does EXP per level affect your ending Base HP?

There was no formal test but rather a personal observation over a few different characters over the past 15 years. Ive had characters where recall was at 50% for long periods of time, characters with high %, and characters with LOW %.

at 50% recall skill, the skill is relatively reliable. There was a definite decrease in its reliability as it increased toward 100%. Due to an unfortunate mistake regarding practicing skills on a trigger loop while at work and the boss coming into the room.... I had a characters skills and spells ALL set to 1%. This of course reduced recall to 1% as well, and I can without a shadow of a doubt confirm that this greatly affected the ability to recall from combat. This all being said. Ability to recall at 100% is nowhere near as low as ability to recall at 1%. but it apears that this ability works best when kept as close to 50% as possible. This makes the "word of recall" spell useful for retaining the emergency ability to rely on the actual recall command. As "Word of recall" % increases so does its chance to succeed. The end result of this is that recall % increasing beyond 50% Does negatively impact your ability to recall from combat.
